CARDING-EN'GINE Specification of Letters Patent.

Original application filed March 26, 1895, SerialN 0. 543,205; Dividedand. this application filed July 28, 1900 v Serial No. 25,088.

T 0 all whom it may concern:

Be it known that 1, DAVID Gnssnnaa .citiadministrator of the estate, ofERNST Guss- NER, deceased, late of Aue, in the Kingdom of Saxony,Germany, who in hislifetime did invent certain new and usefulImprovements in Oarding-Engines, of which the following is aspecification.

The present application is a division of the application filed by thesaid'Ernst Gessner on March 26th, 1895, Serial No. 548,205, on whichapplication Letters Patent of the United States were granted on August21st, 1900, N 0. 656,402.

The present inventionrelates to carding engines, and has for its objectto produce an efiiciently acting carding engine, which will not besubject to objectionable clogging of the card clothing. I Y

' In carding engines heretofore]. roposed, the arrangement of theworkerswit respect to the swift and the mode of working the same havethe disadvantage that the remnants of the fleece and foreign mattersremain in the .card clothing. of the workers. In this manner the cardclothings become gradually clogged and unfitffor, a regular evendistribution, because the card clothing, when in a filled condition, 0crates upon the fleecein amanner difierent "rom themanner in which itwould operate ifclean, andof course in the intermediate stages offilling would operate difierently. It will be seen, therefore, that theproduction will be' uneven. In order to remedy this defectv it hasheretofore been..

necessary to stop the'operationof the machine and clean the cardclothing, This, of course, causes delay and even if the hand card beemployed to effect the cleaning of the card clothing, the working of thema chine is disturbe I.

The objectof the present inventionisto overcome thesedisadvantages.

According to this invention, there is employed astripper'ortransfer-roller, which intervenes between two workers having hook-liketeeth to effect the transfer of a fleece from one worker to another,whereby the workers are not only constantly cleaned, but the up er andless loosened fleece layer taken by t e last Worker from the swift iscarried as a continuous compact layer on the In all the figures roller,as it will be herein designated, is provided with brush-like cardclothing having the, points rearwardlydirected or inclined with respectto the direction of motion of the roller. This roller engages in thecard clothing of the workers, the teeth of which are also rearwardlydirected with respect to the direction of rotation of the workers, andthe workers and. transfer rollers are run at the same or substantiallythe same surface speed, so that the card clothing of the two workingparts-will run in opposite directions at their points of contact, atsubstantially the same rate of speed. The new transfer rollers are alsoin instances so arranged that they come into working proximity with theswift or drum, so that they serve as workers therefor.

In the accompanying drawing is shown diagrammatically several cardingengines embodying the said invention. It will be understood, however,that the various structures shown in the figures may, be used singly orcombined on a single engine.

In the drawing Figure 1, shows a single worker and a single transferroller; Fig. 2 a

plurality of workers and a transfer roller;

' Fig.3 a somewhat similar arrangement; and Figs. 4, 5 and 6modifications of the same general idea. 7 1

g A represents the drum or swift, B the worker C the new stripper ortransfer roller and D the strippers.

InlFig. 1 the stri per or transfer roll C which turns, in the directionofthe arrow, has its teeth rearwardlydirected with respect toits'direction of motion and enters among the teeth of the worker B whoseteeth are. likewise rearwardly directed with re spect to their directionof motion. The transfer roll runs at the same or substantially the samesurface speed as the worker, so that the teeth of the transfer rollandof the worker move opposite to each other at their points of contact atsubstantially the same surface speed. The transfer roll C is locatednear to the drum A and'owing to its position it can act in a twofoldmanner, that is to say, to return the fleece which it has taken from theworker B to the drum A at its outer side and at the same time, owing tothe inclination of its teeth, take up from the main cylinder or drumAacertain portion of the material at Patented May 4, 1909.

. ranged near the drum.

its inner side, which is then deposited on the 1 among the teeth of thesurface of the drum,

surface of the worker B and afterward re turned again to the maincylinder, so that in this arrangement the transfer roll serves as astripper for the worker and at the same time as a worker for the drum ormain cylinder.

These transfer rollers have teeth of a greater length than the length ofthe teeth against which they operate. An additional transfer roller Cmay be arranged to operate upon the worker. This transfer roller issimilar to the transfer roller C and is driven at substantially the samespeed as the worker.

In the construction shown in Fig. 2, the transfer roll C is arrangedbetween two workers B, the teeth of the said transfer roll enteringamong the teeth of both workers. The transfer roll in this constructionis ar- T he two workers B and the transfer roll C rotate in the samedirection so that the adjacent or cooperating card surfaces are movingat their point of contact in directions opposite to each other, wherebythe material delivered up by the lower worker B to the transfer roll Con its outer side is carried by it in a direction opposite to that ofthe drums rotation and is delivered up to the upper worker, from whenceit is returned to the drum. The transfer roll thus acts as a worker forthe drum at its inner side, transferring the material from the upperworker to the drum and taking up a fresh portion of material, giving itto the lower worker which returns it to the drum, the material beingcarried in the direction of the drums rotation.

In Fig. 3 I have shown an arrangement of workers similar to that in Fig.2, but in this case the transfer roll does not serve as a worker for thedrum, but carries material from one worker to the other both on itsinner and its outer side. I have also shown a stripper D in this figure,which stripper may, however, be omitted.

In Fig. 4 I have shown a number of transfer rolls and workersalternately arranged about the drum and close to one another so that theteeth of one roller enter between the teeth of the following roller, thesurface speed of the transfer rollers being substantially the same asthat of the workers. The fleece is worked at the inner side of therollers, each roller taking up a portion of the fleece from the drum andstripping the fleece from the adj acent roller to be transferred to thedrum again, thus carrying the material being worked at the inner side ofthe rollers in the direction of the drums rotation. The lowermost workertakes up a portion of the fleece from the drum, which fleece is thencarried from one roller to the other at their outer side in a direction0 posite to the drums rotation until this fl eece reaches the first or uper roller C which returns it to the drum. pon examining the materiallying upon and it is found that the coarser part or less worked portionof the fiber forms the upper layer on the drum and it is by thisarrangement that this portion of the fiber is taken up by the last rollof the series, and carried back to the first roller to be worked oncemore on the drum. In this arrangement the transfer rollers act asworkers for the drum and the workers act in the same manner in so far aseach of them strips the material from the adjacent transfer roll andcarries it to the next following roller.

In Fig. 5 Ihave shown a worker coo mrating with the drum, a transferroll located close to the worker so as to remove fleece therefrom, and.a stripper for returning the material to the drum.

In Fig. 6 I have shown a series of workers, transfer rolls and stripperslocated between the workers. The action of this medif -ation is similarto that shown in Fig. 4. It will of course be understood that thevarious forms of the invention which I have shown and described areillustrative merely and that I do not confine myself thereto.

It will be understood that in all the constructions shown and describedthe teeth of the transfer roller enter between the teeth of the cardedsurface with which it cooperates, and by reason of the disposition ofthe various teeth and the relative movement of the surfaces, the teethof working rollers or other carded surfaces which cooperate with thetransfer roller will be continuously ground or sharpened in such amanner that they become needle pointed, so that periodical grinding ofthe teeth, as heretofore, is unnecessary.

Having described this invention, what 'I claim and desire to secure byLetters Patent is:

1.. In a carding engine, the combination of a moving card surface, twocurd-surfaced rolls having hook-like teeth in operative relation to saidmoving card surface, and a transfer roller having brush-like teeth whichare rearwardly directed with respect to their direction of motion, inoperative relation to both of said card-surfaced rolls, said transferroller rotating in a like directionv to that of at least one of said.card surfaced rolls.

2. In a carding engine, the combination of a moving card surface, twocard-surfaced. rolls having hook-like teeth in operative. relation tosaid moving card surface, at least one of said card surfaced rollshaving teeth which are rearwardly directed'with respect to theirdirection of motion, and a transfer roller 1 having brush-like teethwhich are rearwardly directed with respect to their direction of motion,in operative relation to both of said card-surfaced rolls, said transferroller rotating in a like direction to that of said cardlflf) l l (lsurfaced rollers which has rearwardly directed teeth.

3. In a carding engine, the combination of a' moving card surface, twocard-surfaced rolls having hook-like teethin operative rela tion to saidmoving card surface, and a transfer roller having brush-like teeth whichare rearwardly directed with respect to their direction of motion, inoperative relation to both of said card-surfaced rolls, saidcardsurfaced rolls and transfer roller rotating in the same direction.

4. In a carding engine, the combination of rolls having hook-like teethin operative relation to said moving card surface, and a transfer rollerhaving brush-like teeth which are rearwardly directed with respect. totheir direction of motion, in operative relationto said moving cardsurface and both of said card-surfaced rolls,- said card-snrfaced rollsand said transfer roller having the same direc tion of rotation.

6. In a carding engine, the combination with the drum, of card-clothedrollers, to-

wit: transfer rollers having brush-like card clothing and workers havinhook-like teeth, arranged about the drum a ternately and in series andin contact with one another and with the drum, so that the teeth of oneroller w-ill enter between the teeth of the following roller and of thedrum, all having theirteeth rearwardly directed with regard to theirdirection of motion, means for driving the same in such directions thatthe contacting card surfaces of the said rollers shall be movedinopposite directions to each other and at the same or nearly the samesurface speed, so as to act as transfer rollers to strip the materialone from another in an unbroken sheet and carry it at their outer sidein direction opposite to the drums rotation from the last roller of theseries to the first of the series, to be thence returned to the drum,substantially as described.

' 7 In a carding engine, the combination of a moving card surface, acard-surfaced roller having hook-like teeth rearwardly directed withrespect to its direction of rotation, and in operative relation to saidmoving card surface, and a transfer roller having brushlike teeth whichare rearwardly directed with respect to their direction of motion andwhich enter between the teeth of said cardsurfaced roller, saidcard-surfaced roller and the transfer roller both rotating in the samedirection.
